Saba's shallow reef and open-ocean pinnacles are protected by a marine park. Most sites are along Saba's lee, and none is more than a 15-minute boat ride from the marina. The island's moored dive sites range from pristine offshore pinnacles to near-shore coral ridges, all encrusted with corals, sponges and sea fans and populated by hawksbill turtles, stingrays and bright tropicals. Standout dives include Diamond Rock, Eye of the Needle and Tent Wall.

You can dive Saba from land-based operations. Dive shops aren't smack-dab on the beach — morning hotel pick-ups and afternoon drop-offs are necessary.
